I am using a 4 mhz xtal, its painfully slow already.. I don't think speed is the problem. I am using shiftout command and sending a C/D bit and then the data. Any other suggestions? I have even tried Daves color lcd program, compiled it, and it works really weird. The colors are not right in 8 bit mode, and the text comes up as just small little lines where the letters should be. I just bough two of these lcds and both do the same thing. Is it possible that epson came out with a new controller. I am using the data sheet that sparkfun supplys and it works in 12 bit mode, besides the freezing but 8 bit sucks. I am also using a resistor divider circuit to step it down from 5v to 3.3.
